Abstract

Official abstract text for this publication.

A method and system to reduce NO x emissions from an engine connected to a fuel tank and an exhaust line, the apparatus including, a reformer to reform the fuel into hydrogen (H 2 ); a fuel cell stack to convert the hydrogen into electricity; a reduction unit disposed on the exhaust line to convert the NO x into N 2 ; a first bypass line to provide a fluid communication between the first fuel tank and the fuel reformer; a second bypass line to provide a fluid communication between the fuel reformer and the fuel cell stack; a first reformate line to provide a fluid communication between the second bypass line and the exhaust line. The hydrogen is mixed with the NO x in the exhaust line, and then the reduction unit uses the hydrogen to convert the NO x into nitrogen (N 2 ).

First claim

Opening claim text (preview).

What is claimed is: 1. A NO x emission reduction system to reduce NO x emissions from an internal combustion engine, the system comprising: an internal combustion engine fluidly connected to a fuel tank; an exhaust line fluidly connected to the internal combustion engine; a fuel reformer to reform a first fuel into hydrogen (H 2 ); a fuel cell stack to convert the hydrogen into electricity, the fuel cell stack fluidly connected to the fuel reformer via a first pipe; a h…
